Be it known that I, JOHN TIN'GLEY, ot' Philadelphie,Pennsylvania, have invented an "Improved Chnrn; and Ido hereby declare the following to be a full, clear, and exact 'description of the same.

My invention consists of a vessel having trunnions adapted to' hearings in a suitable frame, in combination with o. perforated diaphragm and detachable cover, the whole being constructed and arranged substantiallylas described hereafter, for the purpose ofthcronghly agitating the cream, and rapidly obtaining butter therefrom.

In order to enable others to maire 'and use imyvinvention, I will now proceed to describe its construction and operation, reference being had to the accompanying drawing, which forms a part of this specification, and in which- `Figure 1 is a front elevation o' my improved churn. Y

Figure E?, a dertical section of the'samc on the'line 1 2, gl and Figure 3, a plan view, with the end or head of the churn removed.

Similar letters refer to similar parts throughout the several v iews. i

A is a wooden vessel, to the opposite sides of which, at a point about midway between the top and bottom, are sccnred journals or trunnionsb and b, one of which is provided with a crank-handle, c, the t'runnions turning in suitable bearings on the upper portion ofthe frame B, which consists, in the present instance, of,

the standards d and cl', connected together by cross-bars c. The lower ends of the 'staves g' of the' vessel vare bound together by hoopsff, the bottom, g', being secured in the usual manner. The eovert ot` the vessel is detachable, and is secured in its position by a band, t', which has, at one end, a link, and at the other' end a curved lever, 7`,the eccentric portion of `which acts upon the link, and draws the oppositeends of the band 2' together when the lever is moved inward to the position seen in fig. 3, thus tightening the staves, and eiiectnally closing them against the edge of the cover L, as described in the patent granted to'myself on the eleventh day 'ot` AAugust, 1863.. Y

A detachable partition or diaphragm, C, perforated with a num'ber of small holes, lc, extends diagonally across the vessel'A, one end of the diaphragm fitting in the corner formed at thejunction ofthe sides with the bottom of' the vessel, and its opposite endrre'sting in the corner formed bythe cover and sides of thel vessel.

The vessel Ais1 in the rst instance turned tothe upright position shown in iig. 1, and is retained there by means of a hook, Z, which is connected to one of the standards d', and is adapted to avst'aple, m, on' one side of the said vessel. The lever j is first moved out\vard,.the band i loosened, and the cover z removed. Then the cream isintroducedinto the vessel, and the cover is returned to its place, and there secured, after which the vessel is unhooked,rand turned by means Vthe handle c. i`

As the churn revolves, the mass of cream will be projected from one end ot' the vessel to the other, andV on to the diaphragm C, and forced in small streams through the perforaticns c into the body of cream on the other side of the partition, the particles of cream thus being thoroughlyagitated, and the collection of butter from the same rapidly eilectcdfafter which the bandi may be loosened, the cover detached, the diaphragm withdrawn, and the' churn emptied of its contents, and cleansed preparatory to receiving ainew supply of cream.

It'will be seen that, as the diaphragm is `arranged diagonally, the cream can How freely from one end of the vessel to the other, and is therefore more thoroughly'agitated than when a transverse diaphragm-is used, i

while a. diagonal diaphragm may be secured i'n'itsl place without it bein-gl necessary to make recesses in or have projections on the interiorof the churn, which can therefore he thoroughly cleaned, and can afford no lodgment to particles of dirt- I'ciaim as my invention, and desire to secure by LettersPatent The inclined diaphragm, arranged diagonally in the vessel, and held in place by the detachable cover Inf all substantially as set forth. l I i In testimony whereof, I have signed my nametol this specification in the-presenceof two subscribing witnesses,

' JOHN TINGfLEY.
